Hey, everyone

I know this issue has probabaly come up many times in this forum and I had the same issue occur last night and have been looking for a solution as well. i am using windows 8 beta 64 bit and i can only able to connect to the internet through Internet Explorer or some other programs that are built-in with Windows 8, but not all. such as Google Chrome, AVG Updater, iTunes is unable to connect.

does anyone know what could be causing this? many thanks in advance.
